GUNNAR SVE1\T'.DSIEJ1\T TUNE, OF NEW YORK, N. Y.

MASSAGE-VIBRATOR.

To all whom it may concern:

Be it known that I, GUNNAR Sv. TUNE, a subject of the King of Denmark, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Massage-Vibrator, of which the following is a full, clear, and exact description.

This invention relates to a massage vibrator of that type in which the oscillatory element is driven' from a motor through a flexible shaft, the motor being of the water turbine type.

The invention has for one of its objects to improve and simplify the construction and operation of Vibrators of the character referred to so as to be reliable and efficient in use, comparatively inexpensive to manufacture and readily controlled for obtaining different amplitudes of vibrations of the oscillatory element.

A specific object of the invention is to provide a novel, simple and effective connection between the oscillatory element and rotary shaft of the device, which connection is adjustable to obtain a light or heavy vibratory action.

Another object is the provision of an improved mounting for the oscillatory element, of substantial and durable design and insuring rapid movement of the vibrator.

Another object is to provide a form of motor of high efficiency and propelled by water taken from an ordinary city service pipe.

With these objects in view, and others as i will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

illustrate one embodiment of the invention, and wherein similar reference characters are employed to designate corresponding parts throughout the several views, Figure 1 is a view of the apparatus with portions in section to illustrate the details of construction; Fig. 2 is a transverse section on the line 2-2 of Fig. 1; Fig. 3 a view of a crank disk and adjustable connection between the same and oscillator; Fig. 4 is a reverse view of Fig. 3; Fig. 5 is a fragmentary View showing the nozzle and pump arrangement of Specification of Letters Patent.

the turbine; and Fig. 6 is a detail view of the stem of the oscillator.

Referring to the drawings, A designates the body of the vibrator, which is a chambered construction composed of two sections 1 and 2 divisible in a transverse lane and threaded at 3, one within the ot er. The

section 1 has a boss 4, into which is screwed a, handle 5 extending at right-an les to the axis of the body A. Qne end 0 the body has an opening 6 t-hrough which extends the stem 7 of the vibrator or oscillator 8, the latter being detachably connected with the stem so as to adapt the device for different uses. In the opposite end of the body A is an opening 9 having a bearing bushing 10 for the shaft 11, there being on the shaft 11 a crank disk 12 which serves to oscillate the vibrator 8.

The operating connection between the stem 7 and disk 12 is such that the magnitude of oscillation of the element 8 can be adjusted for light or heavy vibrations, according to the treatment to be iven. This operating connection consists o an arm 13 pivoted at 14 on the disk 12 near the periphery thereof, and on the front side, the said arm having an opening 15 which is located at such distance from the pivotal cen ter 14, that when the arm is in one extreme position the center of the opening will coincide with the axis of rotation, in which position the oscillatory element or device 8 will have no vibration. The movementof the arm 13 to its extreme eccentric position i.- limited by a stop 1,6 on the disk, and when the arm is in engagement with the stop the vibrating device 8 has its maximum amplitude of vibration. The arm 13 is moved inwardly and outwardly by means of a finger or wiper 17, disposed at the side of the disk 12 opposite from the arm 13, and cooperat- In the accompanying drawings, which ing with the wiper or finger, which is rigidly connected with the arm 13, is a cone 18 shiftable back and forth on the bushing 9. The movement, of the cone or abutment 18 in one direction is effected by a screw 19 threaded in the section 2 of the body A, and by turning this screw inwardly the cone or abutment 18 is shifted toward the disk 12, and by this movement. the cone wiping on the finger or wiper 17 throws the arm 13 from the periphery of the disk 12 to a central or neutral position, so that the arm 14, as the disk rotates, will cause a reduced vibration of the element 8. A spring 20 is connected with the disk 12 and with the arm 13, so as to operate through such arm to maintain the wiper or finger 17 in engagement with the cone or abutment 18. As the screw 19 is turned outwardly the cone is forced to the right by the action of the spring, and at the same time the arm 13 moves toward the edge of the disk. The inner end of the stem 7 is provided with an approximately spherical tip 21 which enters the opening 15 of the arm 13, so that the stem is oscillated as the disk 12 rotates.

The stem of the oscillatory element or vibrator 8 is mounted on a post 22 which extends upwardly into the stem 7, which has its central portion open at 23 for receiving the post 22, and in this post is carried a pivot element 24 with its axis coincident with the axis of the shaft 11, and the forward end of the pivot 24 engages in a cup bearing 25 arranged in the forward portion of the stem 7. There is sufficient clearance between the stem and the post 25 to allow the stem to have its required range of oscillation. A helical spring 26 is interposed between the rear of the post 22 and the rear portion of the stem 7, so as to urge the latter rearwardly and maintain the socket or bearing 25 in engagement with the fixed pivot 24 and also to maintain the rear end or tip .21 in the opening of the eccentric arm 13. The spring is maintained in engagement with the post 22 by the rear end of the pivot element 24 extending into the spring. ,By reason of mounting 'the stem in the manner referred to and by the employment of the simple and adjustable connection between the shaft 11 and stem, the oscillatory element can be driven at a high rate of speed with comparatively little friction and wear of the parts.

The motor B comprises an annular casing 27 having its bottom open, and mounted vertically in the casing is a shaft 28 which has secured to its lower end the rotary element 29 provided with peripheral tangentially-discharging buckets or blades 30. The shaft 28 passes through a bushing 31 threaded in a boss 32 on the casing'27, and the upper end of the shaft 31 is connected by a helical spring 33, which is also connected with the shaft 11 of the vibrator. This flexible spring 33 of the driving connection between the motor B and vibrator A is inclosed in a tubular protective casing 34 which is flexible by reason of its being in the form of a helical spring wound oppositely to theflexible portion 33 of the driv ing connection. The ends of the protecting tube 34 are rigidly secured'to the motor casing by entering the boss 32, which has an undercut surface or shoulder 35, and extending into the end of the casing 34 is the tapered end 36 of the bearing bushing 31, so that a wedging or clamping action can be obtained on the tubular casing 34. The tubular casing is connected with the vibrator by substantially the same kind of wedging action, this being accomplished by a tapering boss or nipple 38 which extends into the tubular casing 34, and by means of a clamping ring 39 the casing is clamped on the tapering boss 38. To discharge water against the buckets of the turbine wheel a nozzle 40 is mounted in the casing 27 of the turbine with its discharge end in proximityv to the buckets 30. The receiving end of the nozzle has a flange 41 which is clamped against a shoulder or packed surface 42 by a nut 43, The nozzle communicates with an inlet opening 44, to which a service pipe 45 is connected by a coupling device 46. The water discharged from the nozzle 40 strikes the blades of the buckets 30, and after imparting power to the bucket wheel the water drops out of the casing to the open bottom.
